Antibody binding strength against CMV IgG Avidity

The CMV IgG Avidity test assesses the strength of binding of IgG antibodies to cytomegalovirus (CMV) antigens. It can determine whether the CMV infection is recent or past, which is particularly important in the diagnosis of pregnant women.

When to perform the test

The test is recommended when CMV IgG and IgM antibodies are positive in order to determine the duration of the infection. It is particularly important for pregnant women or immunocompromised individuals to assess the risk of complications associated with the infection.

Disease entities

The test is used to diagnose cytomegalovirus, a viral infection that can have serious consequences in the foetus, newborns or people with a weakened immune system.

Symptoms

Symptoms that may indicate the need for the test include fever, fatigue, enlarged lymph nodes, and suspicion of infection during pregnancy or if the immune system is weakened.
